If you are too lazy to calculate then there is nothing to discuss. Just keep being lazy!
Its just simple, exchange pieces and you will win. What is so hard. Instead you were too lazy. Keep it up!
Also, why did you sac your rook. Just play positional. I assume you were too lazy right!
recently, I've had a game in which I was winning, but I got lazy to calculate all variations, so I went for the dull draw. Higher rated opp, so still got points, but please tell how to overcome the following positon. I'm sure there are a lot of crushing moves which I missed, but please give frank advice, and if necessery, harsh criticism.
